from | The angle extends round from this vector. |
to | The angle extends round to this vector. |
Returns the angle in degrees between from
and to
.
The angle returned is always the acute angle between the two vector (ie, the smaller of the two possible angles between them and never greater than 180 degrees).
// prints "close" if the z-axis of this transform looks // almost towards the target
var target : Transform; function Update () { var targetDir = target.position - transform.position; var forward = transform.forward; var angle = Vector3.Angle(targetDir, forward); if (angle < 5.0) print("close"); }
